editorial:auto 13d

The prebuilt library updates urllib3 to 2.7.0 and bumps several dependencies (ty, langchain‑core). A new alpha release of LangGraph is also included.

Why it matters: Patch the prebuilt library to version 1.1.0 immediately; it resolves multiple dependency upgrades including urllib3 2.7.0.
